Beat up the Enemy Hakka Mahou Shaju

The original thread is not very inspiring, so I will replace it with this one. I am a Mahou Soju. It is the kind of Mahou Soju that is said to integrate love and peace, kindness and justice, eliminate evil forces in the world, and protect the happiness of thousands of families (although it is a little different, it is still the same) Now, I have encountered the most serious crisis in history—— I, a genuine and honest child, was reincarnated into this new world without magic! (This is no different from going to the toilet without paper!) What's even more frightening is that this family is completely inhumane. Every day someone would forcefully press my head and brainwash me over and over again: You are an enemy beater, (No, I'm a mahou soju.) He's a professional killer, (No, it's a professional horse monkey.) Getting stronger is your first priority. (No, staying alive is my primary goal!) Mahou soju without its magic power is like a fish out of water, bread has passed its shelf life, and people will die if the express is returned to their hometown. The only source of magic is the power of belief - believing that she is a magical girl is more effective than any magic pill. Now, hurry! How can I convince a family of professional assassins that I am a Mahou soju who knows how to use Mahou? Purpose: Everything is for survival
